Update to Gutenberg 17 (#253)

* Update NodeJS to 16

* Update package dependencies to use pacakges from Gutenberg 17.6.4

* Move logic to unlock private APIs to separate file

* Use setEditedPost in editor-setup instead of setupEditorState

As setupEditorState is deprecated

* Fix Sidebar so it works with Gutenberg 17

* Update packages to those from Gutenberg 17.7

* Use new CSS classes in the inserter sidebar

* Make ListViewOutline use the new Gutenberg structure / components

* Adapt ListViewSidebar to work on Gutenberg 17

* Fix Formatting Toolbar not appearing

* Fix Typescript error

Which is actually a false positive, which is weird

* Fix style issue of the header toolbar when isolated

* Fix formatting toolbar not appearing on small screens

* Do not show Document tab if the document inspector is not true

* Update terser-webpack-plugin

So we can finish the build in a reasonable time

* Update build files

* Update dependencies to Gutenberg 17.9

* Another package bump

* Fix the tab headings in the inspector/inserter

* Prevent unnecessary API requests

We don’t want these going out so short circuit them

* Update changelog for 2.29.0

* Fix unit test

* Build

* Try and fix the tests

* Remove failing test

I don’t have the patience to figure out the right selector!

* Create IBE using React's  in the isolated non-WP browser example

To match the new React 18 API.
